Yes.  We have gradually moved all to an 64bit/release dir, which is a
release area compatible with setup.  Unfortunately upset isn't running
yet and a setup64 is missing, too.

What's also missing so far is coreutils and mintty.  Both packages are
still in 64bit/install.  I'm planning to create a new coreutils package
for the 64bit/release area today, though.

Here's how you can install 64 bit cygwin from 32 bit cygwin without the
base-cygwin-toolchain package for now:

- Download the release area.  It's not that big yet, and it allows
  you to install all packages locally:

  mkdir /tmp/64bit-release
  cd /tmp/64bit-release
  rsync -av rsync:// .

  Additionally fetch coreutils and mintty:


- Set up the 64 bit dir:

  $ mkdir -p /cygdrive/c/cygwin64
  $ cd /cygdrive/c/cygwin64
  $ mkdir -p dev etc bin lib usr home/$USER var
  $ cd usr
  $ ln -s ../bin bin
  $ ln -s ../lib lib
  $ cd ..

- Now you're in the new 64 bit root dir.  From here, run this script:

    for i in $(find "/tmp/64bit-release -type f -name '*.tar.bz2' \! -name ' *-src.tar.bz2' \! -name '*-debuginfo-*.tar.bz2' | sort -r)
      dir="$(dirname $i)"
      [ "$dir" != "$olddir" ] && echo tar xjkf $i && tar xjkf $i
    tar xJkf /tmp/64bit-release/coreutils-8.15-1.x86_64.tar.xz
    tar xJkf /tmp/64bit-release/mintty-trunk-r1306.x86_64.tar.xz

- Copy your /etc/passwd and /etc/group files from the 32 bit distro into
  the etc dir in the 64 bit dir.  Copy your startup and config files
  from your 32 bit dir to your new 64 bit home dir, as created in the
  first step.

- Start a 64 bit shell.  Run the scripts from /etc/postinstall and
  ignore error messages for now.  Copy your desktop "Cygwin Terminal"
  icon and tweak the path to mintty and the working directory in the
  link properties.  Now you should be set up.
